Problem

[nimrex]

Im currently having a problem with my first indoor grow under cfl, I am currently feeding them rain water with a couple of drops of BabyBio to it, I always make sure the soil is nice and moist.

It seems the outa parts of the leaves are curling up and turning brown and also a wierd shiny effect with spots is turning out on some of the leaves.

Included pictures.

Any help would be great?

I'm not familiar with this product. Could you give specifics; ie. what are its N-P-K numbers?

Have you checked the pH of your irrigation water, whether rainwater or tap? Your pH should be in the 6.5-6.8 range for soil.

Bottle reads 10.6 - 1.9 - 1.4, 5-10 drops to 1 pint. I will pop out later and try find a ph test kit.

Here's my advice to you:

1. Check your irrigation water pH regularly. You will need to purchase either test papers (low cost solution) or a pH meter (a bit more costly depending on features). You should adjust pH after adding all nutes, etc., to your water.
2. You need a way to adjust pH up or down, depending on your test results. Some people use household items (citrus juices, vinegar, etc) but I have no info. on that as I've only used the commercial preparations available from hydro shops.
3. Find some better nutes for your plant. From my google search, Baby Bio is an all purpose houseplant food, somewhat like our Miracle Grow all purpose in the states. This won't work too well when you go to bloom this plant as you need very low N and high P and K at that point. I recommend nutes specifically formulated for MJ.
4. Since your plants are 2 months old, they may need to be transplanted. I noticed that your soil looks extremely heavy. When/if you repot, be sure to add about 25% perlite to your soil mixture for additional drainage and to lighten things up some.

But most importantly, you should spend some time reading the FAQs and stickies in the grow forums. They will explain everything you need to grow and harvest this wonderful plant.

Good luck.

A great example of teaching rather than telling. ^^^ :thumbsup:

Thank you so much, Could any of you recommend some sort of better Nute I could get within UK if possible.?

Funny thing is my other plant which is a ceres strain is very very slow growing but the smell and how it looks is amazing.

I don't know what's available to you, your grow budget, or anything else pertinent to this decision. I assume since you're on this forum you have access to a computer. I'm a champion web shopper - I never buy anything locally unless its much cheaper and easier. Do a web search for local hydro shops or if you are able, buy online.

I only recommend nutes I myself have used. I started out using Advanced Nutrients and had excellent results. However, very pricey, many say overpriced. I've switched to Humbolt Nutrients lately and so far, so good. They certainly are a more budget conscious choice. :thumbsup:

Surely there are MJ nute companies operating in the EU if not the UK? Some searching is in order.

I have now repotted them in nice new pots with Mircale Gro pot mix, mixed with about %25 - %30 perlite, I also bought some new feed which is 24-8-16 I wont be using it though as the pot mix already has nutes in for round 3 months (So the packet says), the shop did not have a PH tester, but I am going to order an electronic one from ebay later, although from past experience the tap water and rain water are ok, but maybe the nute I was adding was throwing it, to me it looks like a nute lockout as a stripe in the middle of the fan leaf and spots appear then the leaf dies.

I hope I have caught this in time, if not ill be starting from scratch :( ill keep posting let you know what happens.

Thanks very much for help.

24-8-16 sounds like Miracle Grow All purpose. Use care, as it's real concentrated. I believe I was adding 1/2 teaspoon per gallon, once a week, (when I used to use it) but is not acceptable for flowering. You'll need a mellow bloom fert low in nitrogen. No additional nutes though, till the time release nutes wears-out of the soil.
When you order your ph pen, perhaps you could order some quality nutrients too. Usually best to stick with veg and bloom ferts from the same maker. Prevents imbalances and makes life easier.

I was just gonna say it looks like an over fert problem if I ever seen one.

[polishpollack]

personally, that looks like heat damage. Curling leaves and brown spots usually mean heat damage.

i was told by stinky a long time ago about using rain water. she said that you must add calmag to it....
