Hello all.... So this is my problem, or at least one of them. First go around and I am seeing some twisting on the first couple sets of leaves. I have read that this could be indictative of a pH problem. I have a Rapitest digi soil pH meter as well as a Hanna pH and TDS/EC meter. The Rapitest pos is reading 6.5 for three of my ladies and 6 for the other. Yesterday I watered and collected the run-off and tested with the Hanna. I was getting 7.3 to 7.5. What is my best course of action at this time? I use distilled water, they are under two 2' 4 bulb 6.5K T5's and have been above ground for 8 days.

Soil is 4 part FFOF, 2 part FFLW, 3 part EC, and 3 part Perlite. I use powdered Dolomite Lime at the tune of 2 tablespoons per gallon as well. The soil was prepped for about 2 months as I didn't get to plant as early as I would have liked.

Any input would be very much appericated.

your soil ph is to high. you dont want it to get over 7

I understand that..I should have been more specfic about my question. Twisting leaves in relation to pH and what the experienced grower would do in my situation. Thanks for the reply though.

Have you checked the ph of your water? you shouldn't be getting above a 7 using dolomite. The lime should buffer the soil to somewhere between 6.8 to 7. What are your temperatures running? It could be heat stress. It may also be that your soil mix is a little too hot. If you could post some pictures it would help.

If I am reading your soil mix right, you added earthworm castings to foxfarms ocean forest, so without the pics to say for sure, I'm gonna say its probably an Nitrogen overdose, and since its mixed with your soil your gonna have some work ahead of you. First rule out your suspected Ph problems as Darrmann, Sirus, and Dude suggested. If you tested your first runoff, all you got was the reading of what you put in. Water a bit, wait couple hours, test runoff after 2nd watering. FFOF routinely runs off at 6.5 for me, and my soil probe put FFOF at 6.6. and you added lime so I would not be surprised at a reading of 7. A ph of 7, twisting leaves? maybe slightly. If there is no spotting on the older growth (is there any spotting on any leaves if so where?) and, newer growth as well as older are dark (DARK) green then you may have your answer of an Nitrogen OD. Give us some pics and I'm sure someone will know your answer.

I'm watching this thread. I have similar problems with Root's organic.

Idk why but for some reason im nervous about posting the

pics...I know its dumb, so I will get some up I watered today

(all but the LSD) and I am getting run-off pH of 7.4 ish on the

other 3. I made a uber rookie mistake and got a bit overzealous. I

fed them per Fox Farm's schedule at about 3 days above ground,

and I fed them Grow Big instead of Big Bloom as the chart says.

Needless to say I burnt the shit outta the LSD. I repotted her

and she is perking up. I was hoping the soil mix would help out

with the pH. As far as the others go I am seeing no discoloration

at all (I think)...new growth is a lighter shade of green while the

older sets are darker, no spotting. I hope its not heat stress, I

havent even turned on the 800W of HID goodness yet. I have an

A/C to a C.A.P. controller and my temps dont go above 80...in

fact im having more trouble on the low end of the temp

range. Thank you for all the input guys..I will snap a few pics

tommrow.

Why do u folks add anything to ffof, u don't need to just add water until the 2nd week of flower and u will have no problems. Its a complete soil

I can't speak for all the "folks"... but I mixed FFOF based on advice from another mod on these forums. I will defitinly listen to him next time and not add ferts until much later, but thats the learning curve for ya!

Hey here's another tip, Sirus: you hear a lot of bullshit here so always take everything your read with a grain of salt.
Yeah anyway it sounds like your soil might be hot, yeah, but your 'lings will probably survive it.
