hence, post a pic and lets see

Shriveled leaves... underwatering, micro nute deficiency, nute burn, pH burn, salt burn
yellowing... N deficiency (99% of the times if in veg growth)
i gotta see pics.
honestly, id rather you guys post pics and not say anything, then not post pics and my brain have to try to piece together what your describing.

What does your DWC system consist of and what dose strength are you feeding them??? Most important thing is keeping the pH @ 5.8 and the water temps low.

id add in just about every nutrient. not too much N, and a healthy dose of everything else, including mucro nutes. that leaf rip... i dunno, could be just a rip... but if its on a lot, check for bugs, and keep checking ph.

well if you have too much, dont flush, just dont add more. and if you dont have enough... add more. i doubt you have too much.

Great Thread and postings here..Thanks! Just thought I would add some Pic's of my own..Hope these can help.DSC01918.jpgDSC01919.jpgDSC01921.jpg This is a Calcium deficiency. This was NOT caused by lack of Ca in my mix! I'll explain in a sec...This deficiency was caused due to a lockout! My Ph in my DWC set up rose to 6.2 for a couple days Calcium will get locked out in Hydro above 5.9 and in soil below 6.4 If I would have added additional Ca to my system,I would have created a toxicity! Therefore making matters worse! Before adding more Fert. to treat a deficiency be sure you are checking your Ph levels also! At the first signs of a deficiency,correct your Ph if needed FIRST!...THEN add more fert if NEW growth is still affected. Once a leaf is scarred it will NOT heal! I've seen posts where people expect to see the damaged leaf heal,and when it doesn't they continue to add more fert! BAD!
BTW I am using AN sensi bloom A/B. It already has Ca in it! A/N recommends(on a DWC setup) topping off the res with 100ppmCal/mag(r/o water) which I do. That is why I know it is due to a lock out(plus my Ph reading was obvious!). Thanks for letting me throw my 2 cents in...Grow in Peace!!

HI everyone im growing a clone for the first time and i just recently added nutes and this problem began. its been 4 days now and i was hoping maybe someone could help. ive had the ph at about 6-6.5 in soil.
forgot to mention im using Fossil Fuel, Fox Farms Grow Big, and Roots Organics "Trinity" all at 1/4 strength and i just added them for the first time.
