Nitrogen and Phosphorous Deficiency??

[blink_inc]

I've had quite a time and am learning so much however I can't seem to keep them healthy....

I am watering with tap water.
Adding Botanicare Pure Blend 3-1.5-4 at 1/2 strength every second feeding (water every 3-4days)
humidity is now at 34% however for the last week prior to moving them to their new home, they suffered for two days under 98%.

The temp in their new home is 94F and I know this is high but I have to install my 500cfm inline fan today in the hopes that this will lower the temps...

Grown from seed and approx 7 weeks old now, I have moved them to this new home and hope to flower in a week or so. 12 females out of 16 seeds.

Soil is .9-0-0 with mixed in vermiculite and perlite 6:1 (soil to additive)

Run off PH is somewhere around 6+ (I have really cheap test strips)

Ladies are in 8" round green plastic pots and I am thinking of transplanting one last time into large "drywall mud" buckets. (2.5 gallon is this necessary?)


My problem is this...since I have moved them to the new room (4wx4hx8L) they have seriously wilted and the bottom leaves are yellowing. They were fine before I moved them. This is the nitrogen deficiency I think...

One of the ladies has reddish almost rust coloured spots on the leaves both at the tips and where the "viens" meet the "artery" on the leaf. This is what I think is a Phosphorous deficiency.

Now, I thought I was using a great product in the Botanicare line???
During my Veg I thought that a higher N is required and this stuff says it has a higher N?


Is my solution to flush with PH adjusted water @ 7, add something high in N and 0-0 for the PK to fix the N deficiency?

Do I add 20-20-20 and that will help with both? (It did once before)

Do I attribute this to the change in environment and continue on as is adding my inline fan, lowering the temps and monitoring, no nutes next feeding?

Since I have read many posts I have confused myself....

Sorry for the quality of pics, my camera is all screwed up and won't focus well. if you need better pics I can try again later today.

Any help would be appreciated.

Thanks.

Can anyone help...?

Your plants look really unhappy......

At 94 degrees you're really cooking them. I can't tell you much about growing in soil as I grow hydro but I certainly wouldn't worry about anything else until you've solved the heat problem since you can't even say which of these things you are seeing are due to heat stress and high humidity.....until you fix them and see what happens.

Keep in mind....I'm not saying you don't have other probs......you probably do but I don't know enough about soil to help you.

Try this link and see if it can give you any tips. Good luck.

I used that post to trouble shoot and wanted some validation of my thoughts...

I am fixing the heat today with an extraction fan and I hope that will lower the temps..

[Weedhound]

Good luck.....hope that solves alot but you'd be surprised at how much heat can do to your plants....and can leave an unpleasant reaction that continues for awhile after you've corrected the initial problem.

Yer rootbound. Very,very rootbound.

Don't forget drainage holes in those drywall buckets.

Good luck.

you may be over-watering, also ... :smokin:

[Dr Goodbud]

first thing is whats your PH do you have a meter /ph everthing before adding to your plants looks like you have a lockout of nutrients ur adding nutrients so the nutes are there but the plant just cant absorbe them yeah get thoses temps down to 90 least in veg not flower below and see how they look you might have to get temps down to 85 they look a little over watered let them dry in between watering do the by weight method pick up the pot/bags when there dry and then when there wet to get a feel for when your plants need to be watered and do your watering/feedings they say that in flowering cycle trichome production really slows at 90 degress indoors thats what I heard get a small swamp cooler if A/C is out of the question

swamp coolers add too much humidity, and will promote mold in your buds ... :smokin:
