NEED HELP...Plants very yellow

[curious101]

so today i went and puchased botanicare's clearex...directions said 7-15 ml per gal...went with 15ml...said to give each plant two quarts of water but i gave all 3 a gallon each because the pots are 17in. (rather large)...post some pics in a week to let u know how they look...should i give em 1/2 strength nutes on the next watering or just give em some time b-4 i begin my nutes every other watering at 1/2 strength?

NEED HELP...Plants very yellow Well, my one plant in the top right corner of room is in week 5 of flowering...others are in week 2...having some real problems in the last week...plants yellowing and crisping on the ends of the leaf...first i thought the lamp was too close which was wrong...gave it a light dose biobizz biobloom, cal mag and liquid karma on sat...plants got worse...any ideas...think it may be ph b/c i had a low ph problem during my veg cycle and added some earthjuice up...did the same today hoping it Rating: 5

[curious101]

thanks for all the advice...i was wondering what time frame u were talking when u said it will take awhile for the plants to perk up...u mean like a week or weeks? also how long should i wait b-4 i begin nutrients again...thanks in advance

It can take anywhere from 5-10 days for most strains to recover from any shock or nutrient problem. Monitor your Ph and stabilize it before you feed them again. Most likely Ph was the first problem that causes the second problem.

Check the nutrient availability chart posted in the grow FAQ section. Follow that chart while you finish your grow to avoid problems again. The chart will show you the different minerals available to the plant at variable Ph levels through out your grow.

always wondered...how can u check ph day to day without drowning the plant....isn't the first step in checkin ph watering until run-off and then testing the run off...i assume continual watering during a recovery process is bad...is there another way to check the ph?...or should i have checked the ph after my 1st watering (which means i already messed up)...definitely need help...thanks

plants are beginning to look much better...figured out the problem i had continual ph issues...was mixing my nutes with the suggested ph level for hydro 5.2-5.9 instead of the in soil recommendation of 6.2-6.5...my ph must of dropped badly every time i fed em cuz the ph was so low...they're recovering slowly but surely and are not takin up nutrients i believe b/c of the adjusted ph of the nute mix and the flush...thanks guys....pics coming soon

[curious101]

ok, so the plants seem a little stuck still...like they need a boost...u think a very dilluted foliar spray with bio-bloom would help or just further irritate my plants?

It looks like a PH problem to me. Have you checked your water source? I had some like that before and it was the PH.

[curious101]

no i think i was overfeeding them...flushed em again and just keeping my fingers crossed

flush and start over with recipe paying careful attn: to ph.........is my best guess

Well in soil you cshould use a proper ph tester. They are found at wall-mart, Home depot and any garden store. They will cost you less then 12.00 usd. It's a combo moisture/Ph soil meter.

You balance the water you use yes but the run off is one way to monitor the PPM and the used salts. Much the same way you can use a brix meter as way to check how your plant is doing on the nutrients you are feeding them.


You may want to pick up some CalMag Plus and use it with every watering too.
